need replacement coil balance hardware for Milgard double hung window

Question

Hi, I would like to buy replacement coil balance hardware for a Milgard double hung window. The coils for the upper sash broke as shown in the attached photos. I figure I might as well replace the coils for the lower sash while I'm at it because they probably aren't far behind. The coils for the upper sash are single coils, while the coils for the lower sash are double coils. I attached three pictures of the upper sash coil and two pictures of the lower sash coil.

Hello there!

Thank you for reaching out to us. Our 15-111 appears to be a match. The Series 160 are the compatible coil springs and it looks like yours have stamps that indicate the spring weight.

For the spring stamped with #9.0, see the S160-9.

For the spring stamped with #4.5, see the S160-4.

For the spring stamped with #5.5 S160-5.

You can reuse the old spring supports if they're in good shape.
